- People comparing multiple chart traditions from one birth record instead of re-entering data across separate sites.
- Users with uncertain birth time who need honest low-confidence labels before they trust hour-sensitive facts.
- Students, practitioners, and note-takers who want structured chart data they can save, print, and check later.
- Bilingual households and global users who need English and Chinese navigation around the same calculation boundary.
Free chart calculator
Calculated. Readable. Yours to keep.
Run deterministic BaZi, Zi Wei, Western astrology, and Jyotish chart calculations, then export chart facts as Markdown, JSON, or print/PDF.
- One free calculator flow covers four chart systems while keeping each method separated.
- The app is useful before any interpretation: calculation basis, confidence state, unavailable fields, and export are all first-class content.
- Static guides and articles explain method boundaries for humans, reviewers, and search crawlers without requiring a generated reading.
- The product is explicitly not an AI fortune-telling project: it computes chart facts and leaves judgment outside the app.
- BaZi pillars, stems, branches, hidden stems, Ten Gods, and time-basis labels when supported.
- Western placements, signs, degrees, houses, aspects, lunar phase, and house-method labels when exact time supports them.
- Jyotish sidereal placements, nakshatra fields, dasha anchors, and Sade Sati labels when verified engine fields are present.
- Zi Wei Dou Shu palaces and star fields only when exact-time chart data and runtime support are available.
- No generated readings, predictions, advice, remedies, coaching, diagnosis, or psychological profiling.
- No guessed birth hour: unknown-time charts preserve low-confidence, approximate, or unavailable labels.
- No blended composite score or trend layer; each chart system stays separated by method.
- No paywall around chart facts; the export keeps the calculation record portable.
